Battle of Maritsa

The Battle of Maritsa or Battle of Chernomen took place at the Maritsa River near the village of Chernomen on 26 September 1371 between Ottoman forces commanded by Lala Şahin Pasha and Evrenos, and Serbian forces commanded by King Vukašin Mrnjavčević and his brother Despot Jovan Uglješa.
In 1354, the Ottomans acquired Gallipoli. From there, they expanded into Thrace, taking the important city of Adrianople in 1369. They reached the borders of Uglješa's lands. Uglješa tried to create a coalition against them. He failed to secure support from the Byzantines and the Bulgarians. Most of the Serbian lords were occupied fighting each other and the only Serbian lord who supported Uglješa's ideas was his brother Vukašin.
